Similar to beer, not all lubes are the same. I took a chance on this after a not so great experience with a different silicone lube, and I'm really glad I took the chance. This is an affordable silicone based lube that really can do no wrong. A little goes a long way, and you can use it for things other than sex.

If you are thinking of venturing via mass relay into the "star system" of silicone lubricants, this is the lube for you. It doesn't quite live up to the claim of mimicking body fluid. However, Bodyfluid does make a wonderful massaging medium and lube for intercourse, masturbation and anal play.
